Preparing Your HVAC System for Fall Allergies and Temperature Swings
Simple Steps to Breathe Easier and Stay Comfortable as Indiana Weather Changes

Preparing Your HVAC System for Fall Allergies and Temperature Swings in Indiana
Fall in southern Indiana means beautiful leaves, cooler nights—and a sudden spike in allergy symptoms and temperature swings. Your HVAC system is your first line of defense for both comfort and air quality. Here’s how to get it ready for the season.
Why Fall Demands Extra HVAC Attention
- Allergy triggers: Ragweed, mold, and dust mites peak in autumn, making indoor air quality more important than ever.
- Temperature swings: Indiana’s fall can go from 80°F afternoons to 40°F nights, putting your system through its paces.
Steps to Prepare Your HVAC System
- Change Your Air Filter: Replace your HVAC filter every 1–3 months (or more often if you have pets or allergies). A fresh filter traps pollen, dust, and mold spores—helping your family breathe easier.
- Schedule a Professional Tune-Up: A licensed tech can clean coils, check airflow, and ensure your system is ready for rapid temperature changes.
- Clean Air Vents and Ducts: Dust and debris buildup can worsen allergies. Vacuum vents and consider professional duct cleaning if it’s been a while.
- Upgrade to a HEPA Filter: If allergies are severe, ask about high-efficiency particulate air (HEPA) filters or whole-home air purifiers.
- Check Your Thermostat Settings: Program your thermostat for cooler nights and warmer days to maximize comfort and efficiency.
Signs Your System Needs Attention
- Persistent allergy symptoms indoors
- Uneven temperatures from room to room
- Strange odors or increased dust
